Track laptops over the internet

Hi all

What is the way to track laptops over the internet?

In order to answer this, we first need to know exactly what are you trying to track? The physical device when it is turned on? The physical device when it is turned off? Software on that device?

Both - we need to know when the device gets turned on and host name etc details.

And 2nd what s/w are installed in that machine.
